from a particular grab sample is proportional to the flow at the
time it was taken. At large plants and industrial wastes use
automatic sampling devices that can be programmed for desired
sampling method, that is, grab, continuous, or flow proportional
composite.
4.7.3.2
Sample Volume and Preservation. Volume and
preservation requirements depend on: (1) the analytical
determinations to be carried out on the sample, and (2) the time
between sample collection and analysis. See Table 24 for
recommendations for sampling and sample preservation. Refer to
American Public Health Association (APHA) Examination of Water
and Wastewater and EPA PB 84-128677, Manual of Methods for
Chemical Analysis of Water and Wastes, for specific
recommendations regarding sample containers, volumes, and
methods of sample preservation for each analytical measurement.
4.7.4
Analytical Methods. Analytic methods available for
quantitative determination of physical, biological, inorganic
chemical, and organic chemical characteristics of wastewater
samples are summarized in Table 25. Refer to APHA Examination
of Water and Wastewater for detailed laboratory procedures.
4.7.4.1
Routine Testing During Plant Operation. A routine
sampling and analysis program to maintain plant operability and
performance is required. This program is unique to the
individual industrial and oily wastewater treatment facilities
and a general program cannot be developed by this manual.
The program should be fully developed in the
Operations and Maintenance Manual and revised accordingly after
plant startup and the 30-day performance certification period.
The program should include the following: sample locations and
method, sample type (grab or composite), sampling frequency, and
analyses required per sample. The Operations Manual should also
identify minimum reporting requirements for regulatory
compliance and should provide operating log sheets for recording
operating data.
